In AF the accents in b. 139-140 are clearly shorter than the three previous ones in b. 134, 136 and 138, hence we reproduce them as short. However, if we were to compare them to the distribution of the notes, it would turn out that they are actually the same length – each reaches more or less the middle of the triplet. Therefore, it is most likely that Chopin meant all of them to be long accents, the way it is clearly shown in GE.
